World's most honest cities: The wallet test

Reporters from Reader's Digest dropped some 192 wallets in parks, near shopping malls and on sidewalks
in 16 cities from around the world in a test to find out whether or not
people who picked them up would contact their owners to return them.
Each wallet contained about USD$50 in local currency, a mobile number,
business cards and a family photo. They received surprising results. Check out the breakdown of the number of wallets (out of 12) returned in each city.
